摘要:

本文根据航天部标准《固体火箭发动机测量不确定度的评定》(QJ1275-87)方法,分析综合了“固体火箭发动机0.5%高精度测试系统”推力测量相对总不确定度,结论为0.3%,为全面贯彻该部标提供了应用实例.

Abstract:

In this paper, the uncertainty on thrust measurement in 0.5% high precision measuring system of solid rocket engins which has passed the acceptance, is analyzed according to Aero-Space Ministry Standard QJ1275-87"The Estimation of Uncertainty on Measurements of Solid Rocket Engines".It is shown that the relative uncertainty of the thrust measurement is 0.3%, as an applied example to carry out the ministry standerd.
